I've got the Ciener slide on my 1911 Govt and I love it ... except the magazines. The first round I load just sort of floats in there, the 2nd is loose, and only when the 3rd is put in does the spring really feel engaged. Of course Ciener doesn't have a contact form or email on their website, and I'm way out of their normal business hours for a phone call, so I thought I'd post it here.
Which mags do you prefer? I saw EAA made some out of zytel, but I've not found any other plastic options. I'm guessing most will be steel or aluminum.
